Multivariable adjusted odds ratios and 95% confidence intervals for the lowest quartile of bilirubin subtypes compared to the highest quartile of bilirubin subtypes according to cigarette smoking in current male smokers

¹The number of the lowest quartile of bilirubin subtypes (total bilirubin, direct bilirubin, indirect bilirubin).

²Adjusted for age, alanine aminotransferase, gamma-glutamyltransferase, uric acid, body mass index, and alcohol consumption.
